To create a ratio table based on the given information \(3\) males and \(5\) females, we can use the ratio of males to females, which is \(3:5\).
Let's set up the ratio table:
| Males | Females | |-------|---------| | 3 | 5 | | 6 | 10 | | 9 | 15 | | 12 | 20 | | 15 | ? |
To find the number of females when there are \(15\) males, we can continue using the ratio.
The relationship between males and females can be expressed as follows:
\[ \text{Females} = \left(\frac{5}{3}\right) \times \text{Males} \]
Plugging in \(15\) males:
\[ \text{Females} = \left(\frac{5}{3}\right) \times 15 \]
Calculating that gives:
\[ \text{Females} = 5 \times 5 = 25 \]
So when there are \(15\) males, the number of females would be \(25\).
Now, we can fill in the last row of the ratio table:
| Males | Females | |-------|---------| | 3 | 5 | | 6 | 10 | | 9 | 15 | | 12 | 20 | | 15 | 25 |
Therefore, if there are \(15\) males in the class, there would be \(25\) females.
